Grantham Scholar Gareth Williams is a PhD researcher in the Department of Chemical and Biological Engineering. His PhD project is titled ‘Bioinspired photocatalysts for renewable hydrogen production from organic waste’.
With an average daily energy provision of 10^22 J – far exceeding current global annual energy demands – the sun represents the greatest renewable energy source available. Harvesting visible light and converting it to appropriate forms of energy therefore has the potential to meet current sustainability requirements by (i) covering future energy demands and (ii) overcoming the serious environmental issues related to the use of fossil fuels.
Sustainable hydrogen has the potential to be a concrete alternative to fossil fuels, and Gareth’s project aims to discover and design bioinspired – or green – photocatalysts for selective photoreforming of organic waste to produce sustainable hydrogen.
